circle, the latter type being commonly known as oscillating fans.

Manifestly, fans of the oscillatory type cannot deliver a gust of air simultaneousl along every degree of the arc through whic they swing and so it appears that an object wit in this arc intermittently receives a gust of air durin the travel of the fan. l

It is there ore the primary object of the invention to produce a device of the above mentioned character wherein a constant gust of airmay be delivered from a plurality of" points during the operation of the fan, to the end that all-points positioned about the device may receive the cooling breezes simultaneously `and constantly as desired.`

Another object is to provides. novel form' of housing for the operative-parts 'of the device wherein ri idity of structure and the facility 4.oli assemlingand removal of said parts are paramount features. l

' Another object of the invention is the proand ornamental in appearance, and further 5o within the casing asia unit.

stricted to a single direction, or delivered l within an arc generally larger than half a..l

duction of an outer casing which is attractivel mechanism may be removedv and assembledl With these objects in view, together with others which will appear as the description roceeds, the invention resides in the novel ormation, combination, and arrangement of parts, all as will be described more fully 55 hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In` said drawings:

Fig. 1 is a plan view of the device. Fig. 2 vis an elevation, with parts broken 60 away to illustrate the housing and its contained mechanism.

Fig. 3 is a sectional view of the housing I 'l removed from the casing, and taken substan-A tially on the line 3-3 of Fig. 2. y

Fig. 4 is a horizontal sectional view, slightly enlarged, and taken on the line 4-4 of Fig. 2; and

Fig. 5 `is a similar section taken on the` line 5-5 of Fig. 2. 1 l 70 f The essential parts ofthe device, speakingv broadly, have been reduced to a minimum, in orderv that the article ma be produced with-l in a; reasonable cost an disposed of to the consuming public at an inexpensive figure. To this end, the main casing is designated by the numeral 5, in the drawings', which in thepresent instance .isrect'an ar or boxlike -in construction and comprisesside walls 6, 7, `8 and 9, with both ends open. It will. 80 further be observed that each o f said' side walls are provided with a plurality of apertures or perforations 10 to permit the escape of the air, as Will presently appear.

The housing, generally denoted b numeral 11, is somewhat similar in con guration to said casing 5 and includes side walls 12, 13, 14 andl 15, 'and a top portion.16, the bottom being left open to facilitate the assembling or removal of the mechanism therein. It will, of course,'be understood that both casing and housing may be circular in cross-section, and that the showin of rectangularvmembersfis `but an exemp iiication 'of one of' rthe orm'sfof the invention.

Uponrinspection ofY Figs. 2,'4 and, it

'will be noted that said housing 11 i's maintained inlspaced relation within said casing 5 /by 'means of sleeve members `17 ,which in the present example of the inventionare pothe 35 y from an object on which the device may be placed, by means of legs 19, Which permits the free circulation of air into the structure. The top of said casing is closed by. a cap member which has its depending flange 21 secured to the .upper portion of said casing, as indicated at 22, said cap member 20 be`l in'g somewhat decorative and having a transparent top 23 of varying designs.

As pointed out hereinbefore, the motive or operating parts of the device are positioned within the housing 11, said partscomprising a motor 24vhaving the usual connections for attachment to asource of electrical energy, one end of the shaft 25 being supported in a bearing 26 and carrying a spur gear 27, partially extending into an opening 28 formed in vthe top platform 29, the latter supporting both motor and bearing 26 and having oppositelydisposed side anfes 30 to facilitate its attachment Within the housing, as shown at 31, (see Fig. 2). I further provide a bottom latform 32 which has its oppositely arranged epending flanges 33, vsecured, within said housing, as indicated at 34, said flanges 33 and y the flanges 30 of said platform 29 being arranged at ri ht angles'to each other for assuring a bin 'ng strength to the structure, as will be readily understood. I

Upon inspection of Fig. 2 it will b'efob-y served that said spur gear 27 meshes with a gear 35 carried by a stub shaft 36, rotatably. mounted in bearing 37 rising from said platform 32, one end of said shaft 36'being prof.k vided with a fan 38 positioned between said housing and casing, while its other end carries a bevel ear 39 enmeshed with a horizontally disposed bevel gear 40. ASaid bevel gear 40 is rotatably borne by a ball-bearing support 41 secured to said platform 32 by means of a bolt 42 or the like, the head portion 43 thereof and the nut 44 coo eratingto maintain the ter to lother enmeshed beveled ee parts in stable association.

Obviously bevel gear 30 b ,the gears an shafts aforesaid, is conveye Ato said gear 4G, and it is proposed to transport the yrevolutions of the latgears, anden this point reference should. l'be ad to Fig. 5

wherein it will be observed rthat lshafts 45, 46

and 47 extend radially 'from said gear-40, each bein supported by bearlngs 489 rismg from plat crm 32, the outer ends of each of the shafts carrying a fan 49, arranged between housing, a motor arranged in said remova le the rotation im arted to unison to produce a gust of air in their respective directions. ,i

In assembling the operative parts Within the housing 11, said motor 24 and bearing 26 are secured to said platform 29, whereupon the latter is pushed upwardly within said housing until the holes in the flanges 30. register with the redrilled holes in said housing and then the astening means 31 may be applied. After the motor has been placed,then platform 32, which has been equipped, as shown, is also and similarly placed.

In view of the open bottom of said casing 5 and also since it is spaced from a supporting obJect by means of legs 19, anabundanee of air is su plied to the casing for expulsion by means o said fans lmounted between said casing and housing. The apertures 10 permit the escape ofthe air in the proper directions and the side walls of the casing serve to rovide baling means to distribute the eJectment of the air through said apertures. I' `While the (plaisent is a disclospre of the preferred embo ent of the invention, it 1s to be understood that the-same is not limited thereto, as various changes-in the minor details of construction, proportion and arran ementl of parts may be resorted to without epartm from the spirit of thee invention as efine in the appended claims.l

I claim: i. 1.v A. device of the charaoterdescribed comprising a perforated casing having an open bottom, a housing within and s aced from 'said casing, a plurality of angular y dis osedv 'Sfans posltioned between said casinga housm and a single source of power mounted said in said ousin for operating said fans simultaneously, sai

through said perforated casing.

2. A device of the character described comprismg a perforated casing having an open bottom, a `housing' within :and spaced` from said casing, a plurality of 'angularly disposed and said easing, a

fans positioned between said casini platform for supporting said motor, said vp atform i being `'aositioned within said casing, a second platform positioned be- .'low `said first-named platform, a bevel gear rotatively borne by said second platform, and

apluraliig1 of beveldgears operatively connecte to sai fans an vmeshing with said bevel gear andadapted to be driven by said motor. In testlmony whereof I ax my si ature. "1' BERNARD'FU ER..
